Wolf Man

Wolf Man is Ame and Yuki's father and the husband of Hana, who became a widow after his death. He has the ability to transform into a wolf; this ability was genetically passed to his children.

He was a college student, frequenting the same college as Hana, which is where they had met for the first time. He also worked as a furniture mover and delivery man.

The cause of his death is unknown. But it might be that he fell down in a canal whilst preying for a bird.

Wolf form
In his wolf form, Wolf Man appeared to be an adult wolf with black, grey and white fur. The fur on his head resembled his hairstyle as a human. He had blue eyes.

Clothing
As a human, Wolf Man usually beared a white shirt with dark blue sweatpants. Outside, he wore a black winter coat with a white fur collar, with his white shirt underneath.

As a wolf, he didn't wear any clothing, except when he turned into a wolf for the first time in front of Hana, where he kept his winter coat and shirt on whilst transforming.
